——normalizing relations between the Arab countries and Israel in exchange for a full Israeli withdrawal to the pre-1967 lines...——
Pre -1967 ?
Never ever going to happen
By "pre-1967" they mean "pre-1948" -- no Israel. But it's meant to imply pre-Six Day War. Neither is feasible or acceptable, even if the ethnically undifferentiated Arab squatters on Israeli territory negotiated in good faith, which they don't and won't. The proposal was dead on arrival.
